AMRITSAR David Cameron on Wednesday became the first serving British prime minister to voice regret for the Jallianwala Bagh massacre, one of the bloodiest episodes in colonial India where hundreds of civilians were killed in Amritsar in 1919.

The killings were described by Mahatma Gandhi, the father of the Indian independence movement, as having shaken the foundations of the British Empire. A group of soldiers opened fire on an unarmed crowd without warning in the city after a period of unrest, killing hundreds in cold blood.

Cameron's visit and expression of regret for what happened stopped short of an apology - but made it clear he considers the episode a stain on Britain's past.

Dressed in a dark suit with his hands at his side, Cameron laid a wreath at a memorial to the massacre, a terracotta-coloured stone obelisk. He then stood in front of the monument in silence for a few moments.

"This is a deeply shameful event in British history, one that Winston Churchill rightly described at the time as 'monstrous'," Cameron wrote in a visitor book, referring to the former British leader.

The gesture, coming on the third and final day of a visit to India aimed at drumming up trade and investment, is seen as an attempt to improve relations with Britain's former colonial possession and to court around 1.5 million British voters of Indian origin ahead of a 2015 election.

Before his visit, Cameron said there were ties of history between the two countries, "both the good and the bad".

"In Amritsar, I want to take the opportunity to pay my respects at Jallianwala Bagh," he had said ahead of the visit. Cameron also visited Amritsar's Golden Temple, Sikhism's holiest shrine.

The British report into the Amritsar massacre at the time said 379 people had been killed and 1,200 wounded. But a separate inquiry commissioned by the Indian pro-independence movement said around 1,000 people had been killed.

Brigadier-General Reginald Dyer, the man who gave the order to fire, explained his decision by saying he felt it was necessary to "teach a moral lesson to the Punjab".

Some in Britain hailed him "as the man who saved India", but others condemned him. India became independent in 1947.

Many historians consider the massacre a turning point that undermined British rule of India. It was, they say, one of the moments that caused Gandhi and the pro-independence Indian National Congress movement to lose trust in the British, inspiring them to embark on a path of civil disobedience.

"MONSTROUS EVENT"

Other British politicians and dignitaries - though no serving prime minister - have expressed regret about the incident before.

In 1920, Winston Churchill, then the Secretary of State for War, called the Amritsar massacre "a monstrous event", saying it was "not the British way of doing business".

On a visit to Amritsar in 1997, Queen Elizabeth called it a distressing episode, but said history could not be rewritten. However, her husband, Prince Philip, courted controversy during the visit when he questioned the higher Indian death toll.

Before he became prime minister, Tony Blair also visited, saying the memorial at Amritsar was a reminder of "the worst aspects of colonialism".

In recent years, British leaders have begun to apologise for some of the excesses of the empire.

Visiting Pakistan in 2011, Cameron angered traditionalists at home saying Britain had caused many of the world's problems, including the Kashmir conflict between India and Pakistan.

When in office, Blair apologised for the 19th century Irish potato famine and for Britain's involvement in the slave trade, while Gordon Brown, his successor, apologised for the fact that British children were shipped to Australia and other Commonwealth countries between the 1920s and 1960s.

India's colonial history remains a sensitive subject for many Indians, particularly nationalists who want Britain to recognise and apologise for its excesses.

Sunil Kapoor, 36, whose great-grandfather was killed in the massacre, said he was pleased Cameron had come but said he would have liked a formal apology - feelings echoed by some Indians on Twitter.

"We have been waiting for justice from the British and Indian government for 94 years," said Kapoor. "If they think it's shameful, why shouldn't they apologise?." He said he was disappointed that Cameron had not met some of the descendants of those killed who had come to talk to him.

Cameron has said the two countries enjoy a "special relationship", a term usually reserved for Britain's relations with the United States.

For now, Britain's economy is the sixth largest in the world and India's the 10th. But India is forecast to overtake its old colonial master in the decades ahead and London wants to share in that economic success.
